Seoul Semiconductor filed a patent infringement lawsuit for infringement of its LED driver patents against SATCO Products (SATCO). Seoul Semiconductor claimed that SATCO is selling various LED lighting products that infringe 11 patents of Seoul Semiconductor’s LED driver technology, including U.S. Patent 7,081,722, U.S. Patent 9,807,828; U.S. Patent 8,513,899; and U.S. Patent 8,716,946.

The asserted LED driver patents are widely used in replacement bulbs in the form of incandescent or fluorescent lamps, wall-mount lights, and ceiling lights. The patented technology covers products with a linear driver for directly operating LEDs under household voltage, a step operation driver for generating flicker-free lights, as well as a dimmable driver for realizing smart lighting.

Seoul Semiconductor owns over 250 patents concerning LED driver technology around the world and has enforced its LED driver patents in several prior litigations spanning the different parts of the market.

“Seoul has invested an approximately 10 percent of its sales revenue each year to innovate technology. Last year, we invested even more to ensure that we are at the cutting edge of technology,” said Nam Ki-bum, Executive Vice President of the Lighting Department at Seoul Semiconductor.
